• F(x) = int(x)
• Domain : -infinity ~ infinity
• Range : all integers
• Symmetry : origin
• Even, odd, or neither?

f-1(x) = int(x)
x = int(y)
it is odd.

• Discontinuities?

limit f(x) = DNE
x-> 0
so it is discontiuities

• End behavior using limits.

lim f(x) = - infinity
x-> - infinity
lim f(x) = infinity
x-> infinity
lim f(x) = -1
x-> 0-
lim f(x) = 1
x-> 0+
lim f(x) = DNE
x-> 0
lim f(x) = 3
x-> 6-
lim f(x) = 5
x-> 6+
lim f(x) = DNE
x-> 6
